Rule 4(e) of the Mississippi Rules of Civil Procedure provides:
(e) Waiver. Any party defendant who is not an unmarried minor or mentally incompetent may, without filing any pleading therein, waive the service of process or enter his or her appearance, either or both, in any action, with the same effect as if he or she had been duly served with process, in the manner required by law on the day of the date thereof. Such waiver of service or entry of appearance shall be in writing dated and signed by the defendant and duly sworn to or acknowledged by him or her, or his or her signature thereto be proven by two (2) subscribing witnesses before some officer authorized to administer oaths. Any guardian or conservator may likewise waive process on himself and/or his ward, and any executor, administrator, or trustee may likewise waive process on himself in his fiduciary capacity. However, such written waiver of service or entry of appearance must be executed after the day on which the action was commenced and be filed among the papers in the cause and noted on the general docket.
